Answer 2

To clarify, it seems like you have provided an expression: "9x в квадрате - 3x + 1". I'll assume you want to simplify this expression. To do that, I'll write the expression in a standard mathematical notation and then simplify it.

The expression is: 9x^2 - 3x + 1

This is a quadratic trinomial. To simplify it, we can't further reduce it as it is already in its simplest form. However, if you want to factor it or solve for x, I can do that as well. Please let me know what you'd like to do with this expression!
